Product Overview
WBR3S is a low-power embedded WiFi+BT module that Tuya has developed. It consists of a
highly integrated wireless RF chip (RTL8720CS), a few peripherals, an
embedded WiFi network protocol stack, the BT network protocol, and varied library
functions. WBR3S has an embedded low-power 32-bit CPU, 512 KB static randomaccess memory
(SRAM), 4 MB flash memory, and rich peripherals. WBR3S is an
RTOS platform that integrates all function libraries of the WiFi MAC and TCP/IP protocols. You can
develop embedded WiFi products as required.
